Fix for https://bugzilla.redhat.com/show_bug.cgi?id=725646
The ec2 driver already knows about bucket location in the 'create_bucket' method. However I forgot to add this parameter to the ruby client. Problem is that if you create a bucket using some region specific endpoint, like s3-us-west-1.amazonaws.com for example, AWS needs you to also specify the location to be the same as the endpoint (i.e., 'us-west-1' for the example here). The AWS info on which locations go with which regional endpoints is here: http://docs.amazonwebservices.com/general/latest/gr/index.html?rande.html (see Amazon Simple Storage Service) marios
